The maintenance mistake of oil tank semi trailer

As a member of the dangerous goods transport vehicle, how much do you know about its maintenance? As we all know, no matter what kind of car is in need of maintenance, but maintenance will also exist misunderstanding,

Mistake 1: Always put too much pressure on the tire. Many drivers like to adjust the tire pressure is very high, think this can save fuel, but also overload, in fact, tire pressure is too high will make the tire ground area is reduced, tread wear is serious, will reduce the braking effect of braking, there is no doubt that it will affect driving safety; But too low tire pressure is not good, too low tire pressure will accelerate tire shoulder wear, but also increase the fuel consumption of the vehicle, will also affect traffic safety and vehicle braking effect.

Myth 2: Always add the engine oil is very full, many drivers are always worried about the engine oil is not enough, always add it full, but many people do not know that too much oil will increase the rotation resistance of the crank connecting rod mechanism, but also make the amount of oil splashing on the cylinder wall increase, too much oil will lead to the combustion chamber carbon increase, engine power decline, thus affecting emissions. In fact, the amount of oil can not be too large, but also can not be too little, under normal circumstances to add according to the scale on the oil scale, oil level Z can not exceed the upper limit of the scale, Z low can not be lower than the lower limit of the scale, Z is the best oil level in the middle of the scale on the position.

Misunderstanding three: the various bolts of the vehicle are fixed too tightly. In general, the bolts of various parts of the tank car have corresponding provisions on the tightening torque according to their different diameters, pitch and uses. The torque bolts that cannot reach the provisions will loosen, and the torque bolts that exceed the tightening will be stretched. We should know the tightening torque of the bolt when tightening the bolt.

Mistake four: Always think that the attachment of the belt is better than loose, there are many tanker car owners think that improving the attachment belt tightness, can improve the refrigeration effect of the compressor, as well as the power generation of the generator, in fact, this approach is wrong. The accessory belt should be kept properly tightened, because the belt is too tight, the bearing load will be too large, the service life of the parts will be shortened, and the belt will be broken, so the Z will eventually affect the normal use of the vehicle.
